Question

Write an equation of the line. Slope 0; through (-3,-1)

Answer 1

Answer:

y = -1

Step-by-step explanation:

Using slope intercept form:

y = mx + b

slope (m) = 0

x = -3

y = -1

The only variable that is unknown is the y-intercept, b. You can find this by plugging the values above into slope intercept form:

-1 = (0)(-3) + b

-1 = 0 + b

b = -1

Since the slope is zero, the "mx" part of equation can be taken out since 0 times x will always be 0. When "mx" is taken out of the equation, b remains.

So the equation of the line is:

y = -1
